"Hello. I'm pleased to meet you. I'm Maylene, and I'm the Gym Leader. I don't really know what it means to be strong, or how I got to be the Gym Leader. But I will do the best I can as the Gym Leader. I take battling very seriously. Whenever you're ready!"

At some point before she battled RYFUBA, Maylene was trapped on her podium by the Trainers in her Gym, who thought it would be funny to trap Maylene behind a pile of tires, which she was not strong enough to move, when she had to go to the bathroom. When RYFUBA arrived, he freed Maylene before battling her, easily defeating her Pokémon. Maylene gave RYFUBA the Cobble Badge before running to the bathroom.
